Abstract

Pada tanggal 28 Januari 2014, bencana tanah longsor terjadi di Kabupaten Jombang, Jawa Timur yang mengakibatkan 14 warga Desa Ngrimbi meninggal di tempat. Bencana terjadi disaat malam hari dimana warga sedang tertidur di dalam rumah, sehingga tidak sempat menyelamatkan diri. Di lokasi tersebut, terdapat lima rumah yang berdekatan dengan bukit. Empat rumah hancur akibat tertimbun tanah longsor. Besarnya longsoran tidak diketahui. Untuk itu diperlukan sebuah penelitian yang dapat mengetahui besaran dampak longsoran dari bencana tanah longsor. Selain itu penelitian ini dilakukan untuk mengetahui seberapa efektifkah penggunaan UAV-Photogrammetry dalam mengetahui besaran tanah longor yang telah terjadi.Penelitian ini menghasilkan peta bencana tanah longsor dan jumlah volume longsoran. Besaran volume yang didapat UAV-Photogrammetry sebesar 10527,032 m³ sedangkan perhitungan volume yang dilakukan dengan menggunakan pengukuran teristrial sebesar 11491,708 m³. Dari kedua metode tersebut didapatkan selisih sebesar 964.676 m³. Pada penelitian ini, pengambilan data UAV-Photogrammetry membutuhkan waktu dan sumber daya manusia lebih sedikit dibandingkan dengan menggunakan metode teristrial tetapi biaya pelaksanaan yang lebih mahal. ============================================================ On 28th of January 2014 in Jombang, East Java. 14 villagers in total were dead on the spot. When the incident happened, residents were resting in their house, where there were not enough time to save themselves. On the location, there were five houses adjacent to the cliff. Four houses were destroyed due to landslides. The volume collapsed during the landslide remains unidentified. Photogrammetry can help in measuring volume collapsed during landslides. This study was conducted to determine how effective the use of UAV-Photogrammetry in measuring the amount of land that collapsed. Compared with the terrestrial methode. This research resulted orthophoto map landslides, as well as counting the number of collapsed volume. The amount of volume obtained by UAV-Photogrammetry methode is 10527.032 m³. as a comparison, the volume calculation obtained by terrestrial methode is 11491.708 m³ . Different volume is 964 676 m³. In this case the data retrieval process done by UAV needs less time and human resources than terrestrial.
